Your supplied files should be saved as press quality PDFs. When creating your pdf it is important to ensure that these simple guidelines are followed.
Either convert the text to curves or embed all fonts.
Please ensure that all colours and pictures have been converted to CMYK when producing full colour work.
The resolution of your images should not be downsampled to less than 300dpi.
If your printed area goes to the edge of the sheet you will need to add bleed. This is where the image is extended by 5mm on each side e.g. for A4 paper (297 x 210mm), your image must measure 307 x 220mm. This is required to allow for tolerances when guillotining the job to size.
